Black Sunday made Cypress Hill's connection to rock and roll more explicit, with its heavy metal-like artwork and noisier, more dissonant samples (including, naturally, stoner icons Black Sabbath). It's a slightly darker affair than its groundbreaking predecessor, with the threats of violence more urgent and the pot obsession played to the hilt. Apart from those subtle distinctions, the sound of Black Sunday is pretty much the same as Cypress Hill, refining the group's innovations into an accessible bid for crossover success.
